Jetpack New Dashboard

The new Jetpack dashboard is much better now, it is really easy to navigate through the available modules and find the details compared to earlier version, also it looks amazing.

You can use the search option to find any available module or use the filter options (newest, category or alphabetical)

Jetpack Settings Page

Head over to the new settings page, now users can bulk activate modules as per requirement. Also, it has quick filter for active and inactive modules in the sidebar to guide you accordingly.

So, now you don’t have to spend time and go through each module to activate or deactivate it.

Site Verification Tools

The newly added verification tool will be really useful specially for newbie WordPress users because many newbie WordPress users install additional plugins to verify ownership with services like Google, Microsoft’s Bing, now you don’t have to install a separate plugin.

All of the Website Verification Services can be accessed via your Tools→Available Tools screen
